Discussions about the pilot area in the village office of Desa Sumber Mulyo
The left sliding gate is still blocked in the south (jalur 6) 25 Nov.
The discussion on 26 November
This picture is made on 17 December
The trash racks in the north (jalur 5) are still not repaired
The newly installed rain gauge
Stoplogs will be added next week (5 Dec)
The gauge needs a connection to the side to be more stable.
The SPD near P 5 in the north
Note the installed observation well.
This was the SDU secondary canal on 14 August 2002
This is the SDU on 25 November 2002 on the same location
This gate near the SDU is still in danger to be overflowed
The tertiary structure has been repaired
In Sep.2003 a fiberglass flapgate has been added to the gate
Many tertiary gates have a problem of sideflow.
Field team
This photo is taken in October. See the mechanized plowing.
The same field on 25 November.
View on 17 Dec.2002
End of February just before harvesting
An example of a broad-cast sowed field after a few days.
Field with 5 days old broad-cast rice during heavy rainfall
TC 12 is about 5-10 days ahead of TC 4 in development
Somewhere beginning February
The rake plowing
The rotator and the rake plow to puddle the soil.
Farmers make the culverts themselves!
The culvert installed
Most likely the sliding gate has to be installed again. The gauge in the middle of the canal will be moved and fixed to the gate.
The pilot project has been explained to all goverment agencies involved in the Tidal Lowlands, including Bappeda (provincial planning agency)
The local workshop has repaired the gate perfectly. The gate stands about 55 cm open. The yellow line and the arrow indicates the point where the gate is closed
P2DR will repair it as soon as possible. It will be in cooperation with the P3A (WUA) and team Robiyanto to plan and conduct the works for both secondary gates
Part of the physical monitoring program
A land level mark should be added to the gate. A few bags against side-flow hazards are required. Proper operation of tertiary gates is essential when pump irrigation is required for a second crop.
Note that the gate operation is set at maximum supply to support the land preparation.. This is the SPD near P 6.
This picture is taken on 17 Dec. 2002. Some weeds start to grow again on the sideslopes.
Broadcast sowing of a flooded field. Most fields are not flooded in this period because the young broadcast rice plant might be killed.
The last maintenance was more than six years ago.
Team Robiyanto will look with P3A what can be done here . The danger is during high tide during high rainfall
This picture on 17 Dec. shows that the tertiary structure has been repaired and can with stand high floods. Operation is yet not possible.. This will be required for the second crop in April, especially during dry spells or when pump irrigation will be required.
Still gate is still leaking, but operation of gate is now possible. At high tide there is a hazard of overflow during high rainfall periods.
Especially during very high floods this is a problem. P2DR will for next budget year 2003 take care for the repair of the tertiary structures. When pump irrigation is required for a second crop all tertiary structures must be operational.
The gate operators of SPD P 6 and P 5. with Pak Cipto, Head Farmers Group (Kelompok Tani) in TC 4, one of the two monitoring areas of the pilot project area.
Tidal Lowlands are also one of the few rice land resources in Indonesia where it pays. Reason: lack of labour and farmers own relatively large holdings
Labour saving techniques are the key word for the development in Tidal Lowlands. No transplanting but broadcast sowing on a large scale.
Perfect equal growth of broadcast rice. Result of the On-Farm water management system. The water levels on the field could be controlled and all seedlings have emerged. There are no drowned seedlings which require re-seeding
The prospects are good for a good harvest. The estimated production is 6 ton/ha field dry husked rice (24% moisture)
The owner of this field explained to us that he was very happy with the On-Farm Water Management program (TAM) of Dep.Pertanian. He could much better control his water levels on his field.
The owner of this field also expressed his satisfaction with the On-Farm water management system. Excess water is drained from the field immediately and there is no hazard that the young seedlings will be killed.
The growth of broad-cast rice rice looks here less uniform than in TC 4. Farmers did here also less on On-Farm water management in comparison with farmers of TC 4
It looks good!
This way all weeds disappear and the soil becomes ready to receive the seeds
The coconut trunks are used for culverts at field level. Location Tertiary 12 in the pilot area.
Connection between field drain with the tertiary canal. Culvert quite shallow installed, but there will be more drainage than irrigation. For soil ripening you need deeper drainage. But this requires full water level control by gates, otherwise hazard of over-drainage! and too long pyrite exposure.
